SPECIFICATION formingpart of Letters Patent No. 748,671, dated January5, 1904.

' Application filed April 18. 1903. $erialNo.153,246. (No model.)

To all whom it may concern:

Be it known that I, ALFRED LEE VINYARD, a citizen of the United States,residing at Slidell, in the parish of St. Tammany and State ofLouisiana, have invented certain new and useful Improvements inWrenches; and I do hereby declare the following to be a full,clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in wrenches, and has for its objectto provide a strong and durable tool of this kind having simple andefficient means for adjusting the aws.

With this and other objects in view the invention comprises anarrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation with thesliding jaw adjusted and set. Fig. 2 is a longitudinal vertical sectionshowing the sliding jaw released.

Referring specifically to the drawings, 4: indicates the handle, havingat its upper end a fixed jaw 5. The sliding jaw is indicated at 6 andhas a shank 7, which is contained in the handle 4, passing through aslot 8 in the jaw 5 and into a socket 9 in the lower end of the handle.The handle is open, as at 1O,'f0r a portion of its length, and along oneof the inner edges ratchet-teeth 11 are formed. The shank 7 hasratchet-teeth 12 adapted to engage the teeth 1-1. A set-screw 13,passing through the handle, engages the shank 7. When the set-screw isloose, the shank may slide freely up or down in the handle. When it isin the position desired, the screw is tightened down, which interlocksthe teeth 11 and 12 and securely holds the shank and its jaw inposition. By this construction a quick adjustment is obtained, and thewrench is strong and durable, having no complicated parts to get out oforder. 7

Having thus described my invention, what is claimed as new, and desiredto be secured by 50 Letters Patent, is-- A wrench comprising a recessedhandle having a fixed jaw at one end and a socket at the opposite end, ajaw having a shank extending into and slidable in the socket,ratchetteeth on one edge of the recess and on the shank,and a set-screwfor interlocking said ratchet-teeth, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED LEE VINYARD.
